A
LONDON (Reuters)—Organic (有机的) fruit，delivered right to the doorstep.That is what Gabriel Gold prefers，and he is willing to pay for it.If this is not possible, the 26-year-old
computer technician will spend the extra money at the supermarket buying organic food.
“Organic produce is always better，” Gold said.“The food is free of pesticides (农药)，and you are generally supporting family farms instead of large farms.And more often than not it is locally grown and seasonal，so it is more tasty.” Gold is one of a growing number of shoppers buying into the_organic_trend，and supermarkets across Britain are counting on more like him as they grow their organic food business.But how many shoppers really know what they are getting，and why are they willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences—but their knowledge of organic food is far from complete.For example，small amounts of pesticides can be used on organic products.And about three quarters of organic food in Britain is not local but imported to meet growing demand.“The demand for organic food is increasing by about one third every year，so it is a very fast-growing market，”said Sue Flock，a specialist in this line of business.

According to a new study，putting preschoolers(学龄前儿童) in bed by 8 p．m.could reduce their chances of becoming overweight or obese later in life by half.Preschoolers are children around the age of 4 or 5.
The World Health Organization says obesity can lead to serious long-term health problems like diabetes，heart disease and stroke.
Researchers from the Ohio State University's College of Public Health have found that young children who go to bed after 9 p．m.are twice as likely to be obese later in life.The researchers wrote their findings in The Journal of Pediatrics.
The lead author of the study is Sarah Anderson.She is an associate professor
of epidemiology(流行病学)．Anderson says that，for parents，the results of the study support the importance of creating a bedtime routine.
She says that having a usual bedtime routine is something “families can do to lower their children's risk” of becoming overweight.
Researchers used data from 977 children for the study.These children are part of a larger project called the Study of Early Child Care and Youth Development.The project follows healthy babies born in 1991 in 10 cities in US.
When these children turned 15 years old，the researchers looked at their rates of obesity.Of those with the earliest bedtimes，only one out of 10 was obese.Of those who went to bed between 8 and 9 p．m.，16 percent became obese.And out of those with the latest bedtimes,23 percent became obese.
The World Health Organization reported in 2014 that the number of overweight babies and young children worldwide had increased from 31 million in 1990 to 44 million in 2012.If that trend continues，the WHO warns，there will be 70 million obese children in the world by 2025.
5．According to the passage，the risk of obesity________. A．can be cut by half if children go to bed by 9 p．m. B．can lead to low blood pressure，diabetes and heart disease C．is the highest at the age of 4 or 5
D．is higher for those children who sleep late at night

【答案】 D
6．The underlined word “obese” in the first paragraph means ________. A．heavy C．fat
B．light D．slim
【解析】 词义猜测题。根据所在句意及其前的overweight(超重)可知，此处应指“肥胖”。故选C。
